MECHANISI FOR SCORING PAPER BOARD, PASTEBOARD, OE FIBER' BOARD.

To all wh-0m 't may concern:

Be it known that l, GEORGE 'W. Swiri, Jr., a citizen of the United States, and a resident of Bordentown, in the county offBurlington and State of New Jersey, have invented certain new and useful improvements in Mechanism for Scoring Paper Board, Paste-board, or Fiber Board, whereof the following is a specification, reference pair, so that .the opposing lines approach each other, whereby the ,scoring is accomplished gradually as the board is passed through the rollers.

. My invention further relates to mecha-i nism whereby a series -of parallel scorings may bev impressed at the saine time upon a single board. To accomplish this, a series of opposing lines of rollers or other instru-v mentalities such as l have referred to, are arranged in radial or fan-shaped relation to each other` so thatA as the board progresses through them, the scoring mechanisms approach each other to an extent sufficient to provide the necessary surplus material required f or the formation of the scoring.

ln the accompanying drawings, Fig. l, is a plan view illustrating diagrammatica-lly the mechanism embodying my invention.

Fig ll, is a vertical sectional view showing the formation of a pair of scoring rollers.

Fig. lll, shows the supporting and adjusting means for asingle set of scoring rollers.

Fig. ZIV, is a horizontal sectional view along the line IV, 11V, of Fig. lll.

Fig. V, shows an alternative scoring mech-- anism in which sprocket chains carrying scoringblanks are employed in place of the series of rollers.

F ig. Vl, shows another alternative construction in which a series of rollers is I opposed by an endless sprocket chain with scoring blanks. f

Specification of Letters Patent.

use of rollers in opposite relation. to that of Fig. Il; in the second case, the use of blanks opposed to blanks; and in the third case, of rollers opposed to blanks. Fig. X, in particular, shows a cross section of the device illustratedin Fig. VI.

ln the preferred form iii which I will describe my invention, the scoring mechanism consists of a set' comprising a line of upper rollers 1, 1, l, and a similar line of lower rollers 2, 2, 2. rlhe peripheries of the upper rollers 1, are provided with tongues 3,-as shown in Fig. ll, and the periplieries of the lower rollers 2, are provided with grooves 4l. The line of rollers 1, is mounted in a housing 5, while the lower rollers are mounted in a similar housing 6. Flach line Yof rollers is connected by means of pinions 7, and intermediatepinions 8, the geared series thus produced being driven at one end of the device by the drivinv'gears 10, 10.

Provision for the lateral shifting of the sets.

without vinterference with their operation by the gearslQ,l 10, may be made in any welly known manner in order to render the-draw'- ing more instantly intelligible, in' this regard, lliaveindicated a key-way and feather connection-,of tliegears to their shafts.

rlhe housingj', i'sboltedagainst the vertical bracket 11', by bolts 12, passing through slots, whereby vertical adjustment is permitted, this adjustment being accomplished by bolts 13, set threugh the horizontal eXtension 14, of the bracket 11. n

Said bracket is supported upon a movable carriage 15, and pivotally held thereto at one endv by the bolt 16. lt is also secured to the carriage at the opposite end by bolt 17, but with interposition of ya slot 18, .which permits the radial adjustment to which reference has been made. For convenience of accomplishing this, the bed carries a stud 20, carrying an eccentric 21, working in an aperture in the bracket extension 111.

A similar set of adjustments is provided for the upper housing 5', which need not b'e particularly described, being suiiiciently shown in the drawings.

rlhe carriage 15, rests upon parallel tracks or ways 25, 25, that are transverse to the ,direction of scoring and are provided with 'shaft 28 (here shown assquared at one end for the engagement of a suitable-crank or key, in order to render thel drawing more ,j

regard) instantly f intelligible in this secondly, a capacity for radial adjustment, angularly with reference to the carriage 15 and the ways 25, in the direction of bodily shifting, by rotation of the stud 2Q; and

thirdly, a capacity for vertical adjustmentk towardsor away from itsopposed line of rollers, which vertical adjustment permits of varying the'inclination of the'housing, so that one end of its line of rollers is .nearer the opposite line than is the other -.end. These adjustments and the means therefor, are, it will be seen, independent of one another, so that each adjustment may be made Without disturbance'of the others. The vertical Yadjustment of the scoring .lines of a setl angularly or otherwise relative to` one another and tothe carriage 15 andthe Ways 25 is also independent o'f-other sets.` Y Referrino now to Fig. I, it Will be observed that four sets 'of scoring :Inech anisms .have been adjusted in position to simultaneously produce four parallel scorings 30, 30, 30, 30, in asingle board at the desired distance from each other. In each scoring mechanismv the housings have been adjusted vertically, so that the opposing lines of rollers Where the board enters are further apart than Where it leaves, thereby gradually ,increasing the depth of thev scoring. It Will also be seen that a radial adjustment of the mechanisms has been effected, so that they are in a fan-shaped relation to each other, by which means the required extra material is provided for the making of the scoring lines. By proper relative divergence (or convergence, if the matter be regarded the other Way around) of the several scoring sets, accurate parallelism of tliescoring lines can be secured. l The lateral shifting and radial adjustments (above referred to) allow the distance apart and divergence of the scoring lines to be varied according to l the character and thickness of the material' operated on and the depth of scoring necessary in different kinds of Work. The relations and action of the lines of scoring members of ,aset'are quite dili'erent from whatwould be involved in mere crimping, since these lines are directly opposed to one another in position, instead of being side by side, and act in opposition to one another on opposite sides of the material operated upon.

Referring to Fig. V, it Will be observed that a variant mechanism for producing the scoring is there shown. Instead of lines of rollers, sprocket chains 40, are mounted on sprocket Wheels 41, every other link of the` sprocket chains consisting of a scoring blank 42. The chains are supported during that portion of their travel Where they are opposed to each other, by backing plates 43, With adjustmentsfarranged to provide for the inclinedvor approaching -relationship of travel.

l In Fig. VI, there is illustrated vanother variant mechanism in Which rollers are elnployed for the upper scoring members and blanks on a sprocket Achain for the'lower scoring members, this being illustrated in cross section in Fig. IX.

In the modifications of Figs. VII, and VIII, the scoring is accomplished in a manner similar to thatv already described, i. e., tongues co operating in .opposition to grooves, and it is, of course, to be understood that these elements are mounted in identical supporting means capable of the several adj ustments characteristic of my invention as hereinbefore noted.

In each instance, therefore, perfect scoring is accomplished through the compound adjustment of the oring elements whereby the material incorporated in the crease is automatically compensated for.

Since my inventionl is capable of various modifications it is to be understood that I the chains during this portion" of theirV .do not desire to limit myself to the precise forms herein illustrated.

Having'V thus described my invention, I
